CDC-funded intervention research aimed at promoting colorectal cancer screening in communities.

BACKGROUND: Although strong scientific evidence has shown that screening for colorectal cancer saves lives, most U.S. adults who are at the recommended age are not being screened. Prior studies suggest that barriers to routine screening vary by race, ethnicity, socioeconomic status, urban/rural residence, health insurance status, and factors related to health care providers and the health care environment. Relatively few studies, however, have identified and tested intervention approaches to promote routine colorectal cancer screening among diverse populations. METHODS: The Division of Cancer Prevention and Control at CDC has funded ongoing projects to develop and test interventions to promote routine colorectal cancer screening among medically underserved populations in Appalachia, the Lower Rio Grande Valley in Texas, the High Plains region of Colorado, and other U.S. communities. RESULTS: This article provides an overview of colorectal cancer screening intervention studies currently funded by CDC that focus on a wide range of populations, including medically underserved persons who live in predominately rural areas, Hispanic and non-Hispanic persons, urban African Americans, persons with low health literacy, and persons enrolled in managed care organizations. CONCLUSIONS: These CDC-funded intervention research projects are likely to contribute importantly to evidence about what works to promote colorectal cancer screening in diverse U.S. communities. .

Lessons learned from developing a tailored print intervention: a guide for practitioners and researchers new to tailoring.

Although some "how-to" guides have been written on tailored messaging, we found no reports on lessons learned from the process of developing a tailored intervention. Such lessons may be useful for practitioners and researchers who are new to tailored intervention development. The authors describe lessons gleaned from the process of developing a repeat mammography tailored print intervention. Lessons learned include the following: Selection of determinants appropriate for tailoring should be based on a theoretic framework and refined through assessment of the target population; researchers should anticipate threats to fidelity of intervention delivery because of incomplete or illogical survey data; fingerprinting enables assessment of intervention dose and how it relates to effectiveness of the tailored intervention; and a systematic process for conducting a systems test is needed to check for inconsistencies and errors before final tailored letter production. These lessons are discussed in the context of challenges and possible solutions for tailored health communication.

Correlates of breast cancer screening among Asian Americans enrolled in ENCOREplus.

This study examines the correlates of mammogram utilization among predominantly low income Asian American women using cross sectional data of women recruited through the ENCORE(plus) program (n = 1,695) between July 1996 and June 1998. Logistic regression was used to examine the independent effect of variables corresponding to Andersen's behavioral model of health services utilization on mammography screening behavior. Foreign-born women living in the U.S. < 5 years and between 5 and 10 years were significantly less likely to have ever had a mammogram than women who were born in the U.S. (OR 0.22; CI 0.12, 0.40 and OR 0.48; CI 0.27, 0.86, respectively). Women 40-49 years old were half as likely to adhere to mammography screening recommendations as women 50-64 years (CI 0.33, 0.76). Health insurance was positively associated with adherence to mammography screening guidelines (OR 1.59; CI 1.02, 2.48). The results of this study highlight the need for health education about breast cancer and mammography among Asian American women. Policy work also needs to be directed toward improving access to health care in this community.

Partners in school asthma management: evaluation of a self-management program for children with asthma.

The "Partners in School Asthma Management" program for inner-city elementary school children comprises (1) case finding; (2) linkage of school nurses, parents, and clinicians; (3) a computer-based tailored educational program; and (4) school environmental assessment and intervention. Case finding identified 1730 children in 60 elementary schools with probable asthma; 835 (96% Hispanic or African American) joined the study. Baseline, posttest, and follow-up measures of asthma knowledge, self-efficacy, and self-management behavior were obtained from the children, and data on symptoms, emergency department visits, and hospitalizations were obtained from their parents. The schools provided data on grades and absences. Each school had a baseline and follow-up environmental assessment. The children in the intervention group showed greater increases in knowledge, self-efficacy, and some aspects of self-management. No differences between groups were found in health status variables, school performance, attendance, or levels of environmental allergens in schools. In 15 schools, an enhanced intervention allowed children and their parents to meet with a project physician, develop an asthma action plan, and receive a 1-month supply of medication; the project physician then followed up with the child's community physician. Children participating in this enhanced intervention had better school performance and fewer absences than the comparison group. Overall, the program was effective in improving children's asthma self-management but not in improving their health status. While the case-finding, computer-based self-management training program and linkage system were successfully implemented, the program failed in creating needed changes in the medical (action plans by community physicians) and physical environments (reduced school allergen levels) of the children.

Measures used in studies of informed decision making about cancer screening: a systematic review.

Interventions to promote informed decision making (IDM) for cancer screening are increasingly common. The resulting body of literature provides an opportunity for a systematic review of measures in use. We searched standard databases for intervention trials and other studies of screening decisions and decision aids, finding 2,110 unique citations (most with abstracts) that we reduced to 104 full-text articles; 36 studies met inclusion criteria (prostate = 20, colorectal = 9, breast = 6, cervical = 1). Two independent coders abstracted data on study characteristics, constructs, and measures. Our findings revealed that most studies measured screening (or intention) and knowledge; fewer measured recommended IDM-related constructs and none measured all outcomes proposed for evaluating IDM interventions. Validity and reliability of measures received inadequate attention in study reports, and conceptual overlap exists among measures. Few IDM measures have been developed/carefully adapted from treatment measures and tested for cancer screening or in diverse populations. We recommend that new and in-progress studies emphasize outcomes beyond knowledge-participation in decision making according to personal preference, satisfaction with the process, and consistency between decisions and values. Also needed is better use of theory to guide conceptualization and operationalization of measures, greater attention to reliability and validity (particularly in diverse populations), more thorough reporting of sources and operating characteristics of measures, and increased emphasis and resources focused on these issues by funders, researchers, and journal editors.

Acculturation and mammography screening among Hispanic women living in farmworker communities.

The relationship between acculturation and mammography screening practices among Hispanic women is unclear due to inconsistent study findings. The purpose of this research was to further investigate the effect of acculturation on mammography screening practices among Hispanic women and to explore the effect of biculturalism on mammography screening. Hispanic female farmworkers (N = 716) who were 50 years of age and older living in communities in Texas, New Mexico, and California were interviewed at their homes. Data collection was conducted from November 2001 to February 2002. Logistic regression models showed no significant effect for acculturation for the entire sample. Post hoc stratified analysis found that bicultural study participants in California were 3 times more likely to be adherent to screening compared to those with low acculturation. Study findings suggest that distinct differences might exist for Hispanic women living in farmworker communities in California, and perhaps other communities not on the United States-Mexico border. Women in such communities with low levels of acculturation can be targeted for interventions to increase mammography adherence.

Repeat mammography screening among low-income and minority women: a qualitative study.

Regular mammography screening can reduce breast cancer mortality, yet low-income African American and Hispanic women underutilize mammography screening and are often diagnosed at a later stage, resulting in increased mortality. We used qualitative research methods to identify factors influencing regular breast cancer screening among African American and Hispanic women. Predisposing factors (including fear of mastectomy and lack of knowledge), enabling factors (including cost and social support) and a reinforcing factor were identified and categorized utilizing the PRECEDE framework. The study identified factors associated with the decision to complete regular mammography screening, and examined differences between African American and Hispanic women who participated in the interviews. Future research should seek to better understand the influence of family/friends, risk perception, and fatalistic beliefs on the decision to obtain regular mammograms.

Correlates of mammography screening among Hispanic women living in lower Rio Grande Valley farmworker communities.

Factors contributing to the underuse of mammography screening by female Hispanic farmworkers aged 50 years and older in the Lower Rio Grande Valley were determined through home-based, Spanish-language personal interviews (N = 200). Questions covered adherence to screening mammography guidelines (mammogram within 2 years), healthcare access, sociodemographic characteristics, and theoretical constructs related to breast cancer screening in the literature. Multivariate findings indicated that adherent women were 3.6 times more likely to have health insurance. Self-efficacy for obtaining a mammogram and decisional balance were also significantly related to adherence; age, income, and education variables were not associated, perhaps because of restricted variation. Results indicate continuing efforts are needed to ensure that medically underserved migrant farmworker women have access to health care services. In addition, efforts to increase their self-efficacy in obtaining a mammogram and to counter negative attitudes and opinions by stressing the positive prognosis associated with early detection are warranted.

The cancer prevention and control research network.

The Cancer Prevention and Control Research Network is a national network recently established to focus on developing new interventions and disseminating and translating proven interventions into practice to reduce cancer burden and disparities, especially among minority and medically underserved populations. Jointly funded by the Centers for Disease Control and Prevention and the National Cancer Institute, the Cancer Prevention and Control Research Network consists of sites administered through Prevention Research Centers funded by the Centers for Disease Control and Prevention. The five sites are located in Kentucky, Massachusetts, South Carolina, Texas, Washington State, and West Virginia. The Cancer Prevention and Control Research Network's intervention areas include primary prevention of cancer through healthy eating, physical activity, sun avoidance, tobacco control, and early detection of cancer through screening. The Cancer Prevention and Control Research Network uses the methods of community-based participatory research and seeks to build on the cancer-relevant systematic reviews of the Guide to Community Preventive Services. Initial foci for the Cancer Prevention and Control Research Network's research work groups include projects to increase screening for breast, cervical, and colorectal cancers; to promote informed decision making for prostate cancer screening; and to validate educational materials developed for low-literacy populations.

Development of a cervical cancer educational program for Chinese women using intervention mapping.

This article describes the development of a program to increase Pap screening behavior among women in Taiwan. Intervention mapping, an innovative process of intervention design, guided the development of this program. The development process included a needs assessment identifying factors influencing Pap screening behavior relevant to Chinese women. The program used methods such as information transmission, modeling, persuasion, and facilitation. Strategies included direct mail communication, role-model stories and testimonials, and a telephone-counseling component. The delineation of specific plans for implementation and evaluation are also described.

Effectiveness of an intervention to increase Pap test screening among Chinese women in Taiwan.

This study assessed the effectiveness of a theory-based direct mail campaign in encouraging non-compliant women, aged 30 and older or younger if married, to obtain a Pap test. Participants were female family members of inpatients admitted to one of the major teaching hospitals in Taiwan during August-September 1999. A total of 424 women were recruited in the randomized intervention trial. Three months following implementation of the intervention, women in the intervention group reported a higher rate of Pap test screening than women in the comparison group (50% versus 32%) (p = 0.002). Women in the intervention group also showed higher perceived pros of a Pap test at follow-up (p = 0.031). Although women in both groups showed an increased knowledge and intention to obtain a Pap, only the intervention group had significantly higher follow-up scores on perceived pros and susceptibility. The results shows that the intervention was effective in increasing Pap test screening among Chinese women within three months. The results also support the use of Intervention Mapping, a systematic program development framework for planning effective interventions.

Correlates of cervical cancer screening among women in Taiwan.

In this study we examine several theory-based psychosocial factors on cervical cancer screening among Chinese women in Taiwan (N = 125). The reliabilities of the scales showed good internal consistence (Chronbach alpha ranged from 0.68 to 0.88). We found that 30% of the women had never received a Papanicolaou (Pap) test, and only 58% reported a screening in the past 3 years (adherent). Intention to have a Pap test in the coming year was higher among screening adherence women (90%) than nonadherents (58%). Multiple logistic regression analysis revealed significant associations between screening adherence and women's knowledge (p = 0.034), perceived pros (p = 0.041), cons (p = 0.000), and norms (p = 0.019) of a Pap test. In addition to identifying screening associated factors, we also provided a basis for measuring important theory-based constructs. Although we developed some scale items for Chinese culture, data showed that psychosocial factors were universally relevant. Future intervention efforts tailoring these factors could potentially impact cancer screening for women internationally.
